L-Erythrose is a monosaccharide that contains an hydroxyl group on the second carbon atom. It can be synthesized by a synthetic scheme involving glycolaldehyde and hydroxylamine. L-Erythrose has been shown to inhibit the enzyme phosphoglycerate kinase, which converts 2-phosphoglycerate into phosphoenolpyruvate. L-Erythrose has also been shown to inhibit dehydroascorbic acid reductase, which converts dehydroascorbic acid into ascorbic acid, and galactitol reductase, which converts galactitol into D-tagatose. The mutant strain of Escherichia coli K12 that was engineered to produce L-erythrose showed a decreased susceptibility to phage infection and an increased resistance to oxidative stress. In addition, the polyol pathway in E. coli was induced by L-erythrose treatment.
Application:
L-Erythrose is a rare aldotetrose that have been used as a chirality factor used in QSAR studies of chiral molecules.
